Highland: walls, weather and approvals
The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Highland fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.

Scotland: planning and regulations
Internal insulation rarely needs planning permission, but listed buildings need listed building consent for internal changes that affect their character.
Work that alters an external wall's construction is covered by the building standards system; many over-cladding projects need a building warrant from the council's building standards team, and Section 6 (Energy) of the Technical Handbooks sets insulation benchmarks.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.

Internal wall insulation in Highland: questions
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
What happens to my radiators and sockets?
They're taken off and refitted on the new wall face. Electrical work is done by a qualified electrician.
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
Do you cover all of Highland?
Yes. We survey and quote internal wall insulation across Highland, including Inverness, Fort William, Nairn, Thurso, Wick. Island and remote addresses are surveyed by arrangement.
Do I need planning permission in Scotland?
In Scotland, householder permitted development rights are set by the Scottish GPDO and are narrower for external wall changes; insulating flats or tenements, changing the appearance of a house noticeably, or working in a conservation area usually needs planning permission. We check your address before quoting.
